Summary
How adaptation increases the intensity of sexual conflict. This project aims to test a theory that a species’ adaptation to its environment may cause sexual conflicts where gene variants increase the fitness of one sex but decrease it in the other. When populations harbour large numbers of these sexually antagonistic genes, adaptation is hampered and extinction becomes more likely. This project will fuse experimental evolution with quantitative genetic approaches to test this theory. Understandi ....How adaptation increases the intensity of sexual conflict. This project aims to test a theory that a species’ adaptation to its environment may cause sexual conflicts where gene variants increase the fitness of one sex but decrease it in the other. When populations harbour large numbers of these sexually antagonistic genes, adaptation is hampered and extinction becomes more likely. This project will fuse experimental evolution with quantitative genetic approaches to test this theory. Understanding sex differences in adaptation and the evolution of sexual dimorphism could enable scientists to predict levels of sexually deleterious variation under changing environmental conditions. Its findings are expected to provide new insights into sex differences in adaptation.Read moreRead less
Detecting sex differences in natural selection. This project aims to develop new genomic approaches for understanding how genetic mutations can differentially affect reproductive success in males and females. Applying novel tests, this project aims to uncover previously hidden genetic conflicts between the sexes. This will provide significant benefits, such as new tools that will be broadly applicable to the wider research community, and help to answer key questions in genetics and evolutionary ....Detecting sex differences in natural selection.

This will provide significant benefits, such as new tools that will be broadly applicable to the wider research community, and help to answer key questions in genetics and evolutionary biology in the current genomic era.Read moreRead less
Recombination and the genomic landscape of speciation. This project aims to evaluate how genomes become different during the origin of species by utilising an innovative system where multiple replicates of the speciation process exist. This project expects to generate knowledge in the area of speciation genetics by exploring the effects of sex, migration and selection on the diversity of hundreds of genomes from an Australian wildflower. Expected outcomes of this project include a deeper underst ....Recombination and the genomic landscape of speciation. This project aims to evaluate how genomes become different during the origin of species by utilising an innovative system where multiple replicates of the speciation process exist. This project expects to generate knowledge in the area of speciation genetics by exploring the effects of sex, migration and selection on the diversity of hundreds of genomes from an Australian wildflower. Expected outcomes of this project include a deeper understanding of the maintenance of genetic diversity in natural populations, and development of a model organism for studying the genetics and ecology of speciation. This project should provide significant benefits including enhanced capacity in evolutionary genetics in Australia.Read moreRead less
Understanding phenotypes: contributions from studying mutations in a model organism. The distribution of fish across aquatic habitats will be determined jointly by the swimming speed and endurance requirements imposed by features of the environment, such as water flow, and by the swimming capacity of the fish. This project will use zebrafish to characterise how body shape and physiology interact to determine swimming capacity.
Exposing the complex and flexible genetic basis to polygenic adaptation: integrating population and quantitative genomic approaches. Using leading-edge genomic approaches, the project will dissect the genetic basis to adaptation across an entire species range. The results will highlight the complex nature of adaptation to environmental change and will deliver new approaches to study it in natural populations.

Summary
Evolutionary and environmental basis of CO2 tolerance in coral reef fishes. This project aims to examine the effects of ocean acidification on coral reef fishes due to increasing atmospheric carbon dioxide (CO2). Physiological performance of fish vary under elevated CO2, but behaviour is consistently, negatively impacted. This project aims to investigate evolutionary trade-offs between behaviour and performance, physiological mechanisms key to compromising, maintaining, or enhancing metabolic pe ....Evolutionary and environmental basis of CO2 tolerance in coral reef fishes. This project aims to examine the effects of ocean acidification on coral reef fishes due to increasing atmospheric carbon dioxide (CO2). Physiological performance of fish vary under elevated CO2, but behaviour is consistently, negatively impacted. This project aims to investigate evolutionary trade-offs between behaviour and performance, physiological mechanisms key to compromising, maintaining, or enhancing metabolic performance under elevated CO2, and the importance of habitat in how fish respond to elevated CO2. As fish play critical roles in marine ecosystems by structuring food webs and driving ecological processes, this information will be critical for predicting the effects of ocean acidification on marine ecosystems and biodiversity.Read moreRead less

A high throughput phenomics facility for pace of life traits in animals: This project seeks to create the first high-throughput phenomic facility for animals in Australia. The molecular revolution has brought unprecedented capacity to understand genetic variation. Genetic variation is now better understood and more easily and cheaply characterised than the physical traits that organisms exhibit. Linking phenotypic variation to genetic variation represents the major challenge in harnessing the power of the biomolecular age. This facility will accommodate animals from marine, freshwater and terrestrial systems across a diverse array of phyla. It will allow Australian researchers to leverage advances in high throughput genomic technologies to address a major bottleneck in biology.Read moreRead less
